Solid-State Lighting: Simple, Fast, Bright, and Stable Light Sources (Adv. Mater. 7/2012)
Light-emitting electrochemical cells (LECs) based on ionic transition-metal complexes operate with air-stable electrodes and are prepared using solution-based technologies. The presence of ions facilitates the formation of doped regions close to the electrodes, which reduces the barriers for electron and hole injection but also leads to exciton quenching. H. J. Bolink and co-workers demon-strate on page 897 the maintenance of optimum performance over several hundreds of hours by driving the LEC with a pulsed current, which stabilizes its dynamic configuration. This modus operandi leads to simple light sources with sub-second turn-on times and lifetimes in excess of 4000 hours.
